20 Experiment to Evaluate Maintenance of Functions of Important Facility, Medical Facility （ Dec. 2008 - Jan. 2009 ）

Test Number: E200805
Shaking table experiments had been conducted to evaluate ability of functional maintenance of medical facilities under earthquake disaster. A full-scale 4-story reinforced concrete building specimen simulating a hospital which contained a stuff station, a dialysis room, an operating room and a patient’s room each furnished with real medical equipment and furniture was set up to reproduce function of the medical facility more faithfully. Two hospitals of different kind of structure each, one for a base-fixed structure and the other for a seismic isolated structure, were compared and evaluated their functional maintenance by shaking table experiments. Comparative video of the experiments shows risk of the aseismic hospital and ability of functional maintenance of the seismic isolated hospital under a near fault earthquake ground motion. But even a seismic isolated structure which widely reduces damages against earthquake in general can be exposed to risk by long-period, long-duration earthquake ground motion such as synthetic ground motion for Sannomaru area, Nagoya from a scenario Tokai-Tonankai earthquake if one fails to take earthquake countermeasures.

Shaking experiments of damage free reinforced concrete bridge pier were conducted at E-Defense. The bridge pier specimen was designed based on the current design specifications; however, the specimen had two special attributes, one was a new material, polypropylene fiber mixed reinforced cementitious composite, used to enhance the ductility capacity of the pier base where the severe damage occurs under strong excitation and the other was 0.4 m round corners in a square cross-section of the pier specimen. The pier specimen was 7.5 m tall and its foundation was 7.0 m long, 7.0 m wide and 1.8 m tall. Weight of superstructure was 310 tons. Shaking experiments were conducted for three days. The specimen was subjected to JR Takatori record (the 1995 Southern Hyogo Prefecture Earthquake) with varying amplitude. Small cracks were found at the base of the pier specimen after design level excitation, which was expected result. After that the specimen was excited twice same as before simulating aftershocks, it developed large crack but covering concrete of the new material did not spall off. It was clarified that damage free bridge pier with the new material enhanced seismic performance.

A series of full-scale shaking experiments on a precast and post-tensioned concrete (PPC) structure were conducted to establish high-quake-resistant, productive and reparable concrete buildings. And experiments on a reinforced concrete (RC) structure with almost the same shape of the PPC structure were conducted to acquire usable data for the future development of seismic design method. In the experiments, both the PPC and RC structures were shaken at the same time (the PPC structure at the front and the RC structure at the back of the video). As for the two 4-story buildings, the story height of each floor was 3.0 m, and the long side of the rectangular plane was 14.4 m and the short side was 7.2 m.

In collaboration with the University of Nevada, Reno in USA and National Research Institute for Earth Science and Disaster Resilience, the shake table experiments on a base-isolated building were conducted to evaluate the effectiveness of seismic isolation technology. Specimen was a five-story steel building and isolation devices were installed at the base of the specimen. In the experiment, two different types of isolation system were used; 1) nine triple-pendulum bearings and 2) combination of five lead-rubber bearings and four cross linear sliders. Base-fixed specimen also excited to compare response of the specimen and behavior of furniture installed in the specimen. The record observed at K-NET Iwanuma station during the 2011 Off the Pacific coast of Tohoku earthquake was imposed. Duration of this record is about three minutes and it affects various structures because it contains long-period components, which resonate with base-isolated buildings, and short-period components, which affects low to middle height base-fixed buildings.

In this study, two cases were used for the experiment: a high-rise building model and a low-rise building model. The high-rise building model was based on a 30-story building with a height of 120 meters. The test specimen consisted of the lowest steel frame, which was designed to produce the same shaking as a 6-story high-rise building, and the two upper steel frames, which were designed to produce the same shaking as a 27-story and 28-story high-rise building. The remaining middle part was replaced with a heavy concrete slab and laminated rubber. In the low-rise building model, the middle part was fixed with steel plates to prevent the laminated rubber from working. The test specimen had the widest floor area of any of the previous experiments, and included office and residential spaces. The office space had a suspended ceiling, incorporating both the line ceiling that has been used in many buildings to date, and the grid ceiling, which is advantageous from the perspective of earthquake resistance. Furthermore, the ceiling also incorporated general equipment such as air conditioning units, as well as firefighting equipment such as sprinklers, fire alarms and emergency lighting, reproducing the same equipment functions as in a real building.

In a project to experimental research large-scale buildings in school facilities, shaking tests were conducted using a test specimen that simulated a gymnasium with the world's largest area of ceiling test specimen, and the damage caused by the falling of suspended ceilings in many facilities during the 2011 Tohoku Pacific Offshore Earthquake was reproduced. Through this experiment, it was possible to capture on film for the first time in the world the process of the metal fittings of suspended ceilings attached to actual buildings coming loose and the ceiling falling. In addition, the effectiveness of the fail-safe function, which prevents human injury by catching the falling ceiling and stopping it from reaching the floor, was also confirmed. Experiments were also conducted on ceilings (earthquake-resistant ceilings) that complied with the technical standards enacted in April 2014, and it was confirmed that they were able to withstand the shaking of the 2011 Tohoku Earthquake, which was more than double that assumed in the design.

31 Shaking Table Experiment to verify Monitoring Technology of Earthquake-induced Damage along Pile Foundation （ Oct. 2015 ）

Test Number: E201505
It is important to assess the state of the ground, foundation structure and lifelines after a major earthquake to determine whether the building can be used as it is or whether repairs are needed, and to maintain the building's functionality and achieve early recovery. However, since these are buried under the ground and the damage cannot be seen, it takes a lot of time and money to assess their integrity. Therefore, in October 2015, the E-Defense shaking table experiment was conducted with Taisei Corporation for the purpose of developing a monitoring system to immediately assess the health condition of the ground, foundation structure, and lifelines as a part of the Special Project for Reducing Vulnerability in Urban Mega Earthquake Disasters. In this experiment, the shaking level was gradually increased to progressively damage the pile foundations supporting the building, and the damage was monitored. In addition, the validity of the monitoring system was verified by comparing the results of the damage assessment using the monitoring system with the actual damage. The series of experiments confirmed that the system can be used to monitor the health of the piles. To put the system to practical use, the appropriate threshold values for assessing the health of the piles and the building will be a future issue.

Since the Southern Hyogo Prefecture Earthquake, there have been demands not only for the seismic performance, but also for the continued usability of important facilities such as hospitals and city halls. Since then, Japan has experienced a number of earthquakes, and in recent years there has been a growing demand for buildings such as houses and offices to be able to withstand earthquakes and continue to be used, in order to ensure the continuity of economic activity and rapid recovery. In order to improve the seismic resilience of reinforced concrete buildings, which are often used for housing complexes, in November 2015 a shaking table test was conducted on a model of a housing complex, with a cast iron bearing (cast iron plate) installed at the base of the foundation. In addition, in December 2015, a shaking table test was conducted using the same specimen, but this time with the base of the specimen fixed to the shaking table. The series of tests confirmed that damage to the building structure could be mitigated by allowing the foundation to slip, and confirmed the building response characteristics during a major earthquake and the process by which the building structure reaches the point of damage.

There are around 200,000 agricultural reservoirs in Japan, but as around 70% of them were built before the Edo period, many of them are now dilapidated. In Hyogo Prefecture, there are the largest number of reservoirs in Japan, with around 38,000, so there are many reservoirs that need to be repaired. In the past, repairs have been carried out using the “Hagane-do” method, which uses impermeable soil layer to prevent water from seeping through. In cases where this method is difficult to apply, there has been an increase in the number of cases using a bentonite-based impermeable sheet method. However, since it is not yet clear how the impermeable sheet and the surrounding embankment behave during an earthquake, and whether they can maintain their water-proofing and durability after an earthquake, a shaking table experiment using a full-scale model was conducted as collaborative research with Hyogo Prefecture and Kobe University to compare the Hagane-do method and the impermeable sheet method. As a result of the experiment, cracks appeared on the top of the embankment in the impermeable sheet method. However, as there was no leakage or collapse after the seismic motion, it was found that the impermeable sheet itself maintained its function.

Test Number: E201602
In the face of the major earthquake that could strike in the near future, improving the resilience of cities has become an urgent issue. In order to improve resilience, it is essential to be able to assess the structural condition of buildings immediately after a major earthquake. As part of the “the Special Project for Reducing Vulnerability in Urban Mega Earthquake Disasters”, in February 2017 an experiment was conducted to verify the structural health monitoring technology for buildings and foundation structures. The experiment was conducted on a reinforced concrete building supported by pile foundations in the ground, with the structure, piles and ground as a single coupled system. In this experiment, two stages of shaking table tests were conducted, consisting of damage to the soil-pile coupled system and damage to the superstructure. In the first stage, damage to the soil-pile coupled system was reproduced by conducting coupled system tests of the superstructure, soil and pile, and in the second stage, damage to the superstructure was reproduced by conducting tests on a building with a fixed foundation. The shaking level was gradually increased, and detailed data was measured until the pile itself and the building were damaged. The series of experiments has provided valuable data that is necessary for understanding the behavior of the coupled system of soil-pile-structure and the process by which each part reaches the point of damage.

35 Large-scale Verification Experiment of Liquefaction Evaluation and Measures to Industrial Complex in Coastal Reclaimed Land （ Feb. 2017 ）

Test Number: E201603
As one of the important facilities, the industrial complex is often located on reclaimed land in coastal areas, and as liquefaction damage is predicted to occur during earthquakes, urgent countermeasures are required. Therefore, as a part of “Cross-ministerial Strategic Innovation Promotion Program (SIP)”, a large-scale experiment was conducted in collaboration with the Port and Airport Research Institute and National Research Institute of Fire and Disaster, with the aim of promoting liquefaction countermeasures for industrial complexes on reclaimed land in coastal areas. Two 1/8 scale model structures were built inside a rectangular container, consisting of a pier-type quay, a bridge, and an oil storage tank. The model structures were then subjected to a simulated motion from a Mw7.3 near-field earthquake. The measurement data and images obtained from this experiment are available.

36 Study on Seismic Performance of Embankment for Irrigation Pond with Impermeable Sheet Method （ Jan. 2018 ）

Test Number: E201706
Prior to this experiment, a collaborative E-Defense experiment on an embankment for irrigation ponds with an impermeable sheet (E201511) was conducted with Hyogo Prefecture and Kobe University on March 17-18, 2016, and it was confirmed that there was no leakage after the vibration and that it was safe. In this experiment, to further confirm the safety of the impermeable sheet method, a comparison experiment was conducted based on different sheet laying methods that considered conditions closer to the actual site and construction conditions again with Hyogo Prefecture and Kobe University. The experimental conditions were a stepped sheet laying method, which is a typical construction cross-section, and a straight sheet laying method. For the stepped sheet laying method, the effects of deliberately modeling the sheet joints that could occur in actual construction were confirmed. In this experiment, cracks eventually occurred in both embankments. Extremely large cracks appeared in the embankment where the sheet was laid in a straight line, and the difference in the stability of the embankment due to the difference in the method of laying the sheet was apparent. However, since there was no leakage in either embankment, it was confirmed that the impermeable sheet itself was functioning.

37 Large-scale Verification Experiment on Seismic Retrofitting Technology of Road Bridge Foundation on Liquefiable Ground （ Feb. 2018 ）

Test Number: E201707
Roads are an essential infrastructure for transporting supplies and providing relief to disaster areas even right after a major earthquake, and it is essential that road bridges can be used immediately after a major earthquake. However, in past earthquakes, there have been many road bridges that have been damaged by liquefaction of the ground caused by the earthquake, and it has taken a long time to restore them. Based on the experience, as part of the Strategic Innovation Program (SIP), a large-scale shaking table test was conducted for road bridges in collaboration with the Public Works Research Institute in February 2018. The aim of this experiment was to clarify the behavior of bridges during earthquakes and to verify the effectiveness of seismic reinforcement techniques. Unreinforced and reinforced test specimens were prepared, with the former simulating old road bridges that are at risk of being fatally damaged by liquefaction, and the latter simulating bridges that have been reinforced using a seismic reinforcement method that can be implemented while ensuring the flow of road traffic, and they were shaken using seismic motion as defined in the design standards. A series of experiments has provided useful data for clarifying the behavior of road bridges during earthquakes. It has also become clear that it is possible to reduce damage to road bridges by using the seismic reinforcement methods tested.
